• Manufacturer Part Number: CXA1726
• Description: Multiplier IC for Displays
• Manufacturer: SONY [Sony Corporation]

Input Signals
Description of Operation
• Multiplier
• Operational amplifier
• Switch
The input X and Y signals of the multiplier are multiplied and output to the OUT pins.
This inputs the signals which have been output from the multiplier.
The signal input from IN1 is selected for "a" side or "b" side by the SW1 applied voltage.
When SW1 is 2V or less, low turns to "a" side; it is 2.6V or more, high turns to "b" side.
The unselected output pin is connected to GND.
Care is required with ringing in the operational amplifier. Placing a 5p capacitor in parallel with the feedback
resistor is recommended as a preventive measure.
For the multipliers with a switch, "a" side or "b" side is selected under the same conditions.
